While revving the engine (at operating temp) during a fuel pressure test ('99 Intrigue 3.8L Series II 168K), I noticed the upper radiator hose collapsing. After letting it cool down, pulled the radiator cap & observed the level down 1 - 2 inches from top of the radiator neck. Topped off the coolant and replaced the cap with a new, 16# one. (There was plenty of coolant in the reservoir, and the car has not been running hot.) Drove the car 5 miles, filled the gas tank & returned - temp ran 197-198 deg. (ScanGauge). Upper hose is still much flatter than normal. Anyone ever seen this? Should I bother replacing the upper hose (sure it's been replaced before, but not sure how long ago)?
